Nina has some nickels and 9 pennies in her pocket. Her friend, Maurice has twice as many nickels as Nina. Together these coins a
algol13

So Maurice would have 2N nickels  

Total number of coins is N + 2N + 9 = 3N + 9  

Each nickel is 5 pennies  

3N of nickels = 15N pennies  

-----------  

Their worth is 84 cents  

15N + 9 = 84  

15N = 75  

N = 75/15 = 5  

N = 5  


This means Nina has 5 nickels.

NO LINKS I NEED REAL ANSWERS <br> what are the 2 missing numbers on the blanks?
zavuch27 [327]

Answer:

Step-by-step explanation:

P1 = (2000, 1000)  in the form (x1,y1)

P2 = (2012, 3400) in the form (x2,y2)

m = (y2-y1 / x2-x1)

m = ( 3400-1000 ) / (2012 - 2000)

m = 2400 / 12

m = 200

y = 200x + 800

Y=2 Enter the solution (x, y) to the system of equations shown 7y+3x=5
AnnyKZ [126]

Answer:

(x, y) = (-3, 2)

Step-by-step explanation:

Put the given value of y into the equation and solve for x.

... 7·2 +3x = 5

... 3x = -9 . . . . . . subtract 14

... x = -3 . . . . . . . divide by the x-coefficient

The solution (x, y) is (-3, 2).

the scale map says that 10cm represents 2km what distance on the map in centimeters represent an actual distance of 15 kilometer
Leno4ka [110]

Answer:

75cm

Step-by-step explanation:

Well, I can't see a photo, so I'll have to assume that the description provides enough info.

10cm/2km = x/15km,

where x is the distance on the map (in centimeters) of a real-life distance of 15 kilometers.

10cm/2km = x/15km

10/2 = 5/1

This means we have to multiply 5 by 15 to find x.

x = 5 · 15

x = 75

Let's plug the new value back in...

10cm/2km = x/15km

10cm/2km = (75cm)/15km

<em>(Simplify each side to its simplest form)</em>

10cm/2km = 75cm/15km

5/1 = 5/1

It works! So x = 75cm.

Hope this helps! :)
